Example Question #11 : Help With Alkene Reactions
The ozonolysis reaction involves the use of 
Esters
Aldehydes
Carboxylic acids
Terpenes
Ethers
Aldehydes
The ozonolysis of alkenes forms either ketones or aldehydes. Subsequent reagents can be added to produces alcohols and/or carboxylic acids.
Example Question #12 : Help With Alkene Reactions
Which of the following is an intermediate in the hydration of ethylene for the reaction given?
The reaction mechanism goes through a carbocation intermediate as follows:
Therefore the answer is the following carbocation intermediate:
Example Question #13 : Help With Alkene Reactions
Which of the followinng sets of addition reactions proceed via syn addition?
Bromination, catalytic hydrogenation
Hydroboration-oxidation, epoxidation
Halohydrin addition, bromination
Bromination, epoxidation
Halohydrin addition, epoxidation
Hydroboration-oxidation, epoxidation
Reactions that proceed by syn addition include hydrogenation, epoxidation, and hydroboration-oxidation. Reactions that proceed by anti addition include halogenation, halohydrin addition and epoxidation followed by ring opening. Syn addition occurs because reagents must approach from only one side of the double bond.
Example Question #14 : Hydrocarbon Reactants
Predict the product of the chemical reaction given.
The reaction given is called a Markovnikov's addition reaction. This is a regiospecific reaction because only one orientation of the reaction occurs. It is an electrophilic addition reaction that involves the reaction of a halogenic acid such as 
Example Question #15 : Help With Alkene Reactions
Predict the product of the chemical reaction given.
The reaction given is called a Markovnikov's addition reaction. This is a regiospecific reaction because only one orientation of the reaction occurs. It is an electrophilic addition reaction that involves the reaction of a halogenic acid such as 
Example Question #15 : Hydrocarbon Reactants
Which of the following would be the product of the reaction given?
Molecular chlorine reacts with an alkene in the presence of water to yield a halohydrin product. Below is the mechanism for this reaction:
Example Question #17 : Help With Alkene Reactions
Which of the following would be the product of the reaction given?
Molecular bromine reacts with an alkene in the presence of water to yield a halohydrin product. Below is the mechanism for this reaction:
Example Question #544 : Organic Chemistry
What is the major product of the reaction given?
Alkenes react with NBS (N-bromosuccinimide) in the presence of light to giving products in the position next to the double called the allylic position. Below is the mechanism for this reaction:
Example Question #21 : Reactions By Reactant
What is the major product of the reaction given?
Alkenes react with NBS (N-bromosuccinimide) in the presence of light to giving products in the position next to the double called the allylic position. Below is the mechanism for this reaction:
Example Question #21 : Reactions By Reactant
What is the product of the chemical reaction given?
Hydroxylation of alkene compounds is called a hydration reaction. The reaction occurs in the presence of a strong acid catalyst to protonate the organic compound similar to Markovnikov's addition forming a carbocation as an intermediate. A water molecule nucleophilicly bonds to the carbocation intermediate. A proton is lost from the positively charged oxygen to a chloride ion yielding the alcohol product and regenerating the acid.
